L. pseudomesenteroides is one of the species of Leuconostoc. An infection caused by Leuconostoc is very rare [1]. It has long been regarded as a necessary bacteria in the production of dairy products, fermentation, brewing, and sugar industry and is not a common pathogen [2]. Since 1984, Lee et al. reported for the first time the infection caused by Leuconostoc, and there have been few reports of human infection [3]. Recently, we have a case of lymphoma patients with diffuse pulmonary infiltration of lesions; lung biopsy used by transbronchial cryobiopsy (TBCB) got satisfactory specimens. In the lung tissue, we cultured L. pseudomesenteroides and confirmed its presence by mass spectrometry. As we know, this is the first reported infection of L. pseudomesenteroides to have been identified in live lung tissues.
